Aye-aye  (Daubentonia madagascariensis)

The bizarre aye-aye is one of the most unusual primates on the planet, so much so that it was originally classified as a rodent (2). The thick coat is slate grey to brown with white flecks from the long guard hairs, which are lighter at the tip (2). The face is paler than the rest of the body with large, leathery ears and prominent, yellowish-orange eyes (2). The hands are the most striking feature of this animal; the elongated, thin fingers have curved, claw-like nails (4) and the third digit is extremely thin so that it appears to be little more than skin and bone (2). The aye-aye is the largest nocturnal primate and has a long bushy tail (4).
